Model Of Research And The Establishment Of Transport Facilities In Simulation Of Transport Hub

Transport Integrated Hub is a collection of a wide range of passenger traffic, passenger travel purposes organisms, is also a number of operations and a variety of forms of organization composed of public transport means the space place. Passenger transport system in a large urban transportation system this complex is the most important component of urban functions with the most closely related to, the greatest impact. Urban road traffic with the rapid development of rail passenger transport system is also the most complex urban transportation, the problems and contradictions faced by the most prominent part. Delayed construction of urban transportation hubs and functional and structural design problems caused by the unreasonable become increasingly apparent, prompting a number of urban transportation transfer low rate, the entire city's transportation system operating efficiency seriously reduced. Construction and Planning of passenger transport hub become a problem in China, one of the city's traffic problems.With the development of society, the relevant factors affecting transportation systems become increasingly complex, and we look forward to solving the traffic problem, from which seeks to find the optimal solution. However, in the real traffic environment in certain areas contain many factors of insecurity, but some areas still need a lot of capital investment will allow us to find the optimal solution becomes very slim. At this point, application of computer simulation technology to simulate the transport hub has become a very effective technical means, he not only intuitive to reflect and identify the hub where the bottlenecks are, but also can evaluate the layout of various types of facilities within the hub of a reasonable degree and eventually to find out a reduced ability to cause a hub assembly sparse factors. However, in many of the traffic simulation software, which aimed at a specific issue mostly traffic simulation to study the transfer of vehicles within the transportation hub and pedestrian behavior theory and simulation software less. And these software are normally filled by hand-drawn drawings, increase the user's workload and to limit the complexity of the map accuracy is difficult to meet the requirements, impact analysis results.Based on the integrated transport hub of internal facilities, integrated transport hub in the classification based on the internal facilities, the establishment of facilities model. On this basis, DXF files with OpenGL technology characteristics and the eventual realization of simulation system in the transport model simulation scenarios, reducing the workload of a large number of users, in order to provide an accurate simulation system simulation model, the simulation can be more normative, analytical the results more accurate.In this paper, the Ministry of Science and Technology of China National High Technology Research and Development Program (863 Program) Special issues (2007AA11Z124) "integrated transport passenger hub function and structure of numerical experiment system" as the basis, Xizhimen Beijing subway hub with the building design and site of the Metro Research hub internal facilities, the use of modeling system Xizhimen subway station in Beijing scene simulation structures. Consolidated passenger hub for the function and structure of experimental system provides a numerical simulation model is correct. The modeling system through the simulation of multiple transport hub to achieve scenario shows that the system has a certain versatility. Passenger hub for the integrated transport system finally finish numerical experiments hub of insider flow simulation analysis, organization of special events downstream flow of program development as well as the comprehensive transportation optimization of the design and operation programs, to provide a theoretical basis for improving and supporting decision-making tools, has played an important role.
